If the marriage never happened an old continuity problem of Spider-Man gets actuality again. I asked myself that since Norman Osborne returned after the clone story: How could Peter ever accept that Osborne got away with the murder of Gwen Stacy? If the marriage never happened Gwen would have stayed the love of Peter's life. Mary jane did not get the love of his life but after the marriage. So if they never married, he wouldn't have forgotten Gwen that easily. So he would be after Osborne. BND never can explain THIS.
